This tutorial model illustrates how to calculate the pressure drop and initial flow rate in a pipe system connected to water tank. The Pipe Flow interface contains ready to use friction models accounting for the surface roughness of pipes as well as pressure losses in bends and valves. En savoir plus
A benchmark model for the fatigue module. A cylindrical test is subjected to non-proportional loading. Three stress based models: Findley, Matake, Normal stress, are compared to analytical values and to each other. The non-smooth behavior of the Matake model is captured and discussed. En savoir plus
Substrate Integrated Waveguides (SIW) can be used in antenna applications. Leaky waves from a slot array on the top surface of the SIW in this model generate a beam in a certain direction that can be steered by choosing a different operating frequency. En savoir plus
The model simulates atmospheric corrosion of a galvanic couple, comprising of an Al-Co-Ce metallic coating and an aluminum alloy, which is in contact with electrolyte film of 100 micrometer thickness. The corrosion inhibitors are released from the metallic coating and are transported ... En savoir plus
This example demonstrates how to import and repair a surface mesh from an STL file, and to create a mesh to simulate nasal spray application inside the human upper airways. It further demonstrates how to combine the repaired mesh with the geometry of a nasal spray, then to remesh and ... En savoir plus
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... En savoir plus
Trusses are structural members that can only sustain axial forces, but no bending or torsion. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This ... En savoir plus
Passive devices can be designed using lumped element features if both the operating frequency of the device and the insertion loss of lumped elements are low. This example simulates two types of lumped element filters that are similar to lumped ports, except that they are strictly ... En savoir plus
The process of filling a water balloon is a vivid example for the interaction of fluid pressure and a nonlinear structural material. This model demonstrates how straightforward a FSI simulation model is set up in COMSOL. En savoir plus
This model shows how to control the position of the base of an inverted pendulum to keep it vertical. The control is performed using a PID controller in Simulink®. The position of the base is constrained within specified limits, and an external force is applied at the base to keep it ... En savoir plus
